August Euler (20 November 1868 – 1 July 1957) was a pioneer German aviator,aircraft constructor and the holder of the first Germany Pilots license, issued in 1909.

The company still worked up to 1920,any additions or corrections are welcome.

May I refer to an excellent two-volume book on Euler aeroplanes, recently published in English: August Euler & His Aeroplanes 1908-1920 by Michael Düsing (originally published in German in 2008 as Abenteuer Gelber Hund. August Euler - Deutsche Luftfahrt ab 1908). The English translation appeared in the series A Centennial Perspective on Great War Aeroplanes.

On pages 246-265 (Volume 2) you can find a list of all the 503 Werknummern from Euler and his Euler Flugmaschinen-Werke in Frankfurt a.M.

One hundred or more were Voisin-like pusher biplanes, mostly without a designation, but some variants got names as Großherzog, Gelber Hund (with subvariants Kleiner and Großer Gelber Hund), Hessen, Flugsport.

Later Euler built a nummer of monoplanes, biples, triplanes and even a quadruplane. The factory stayed very small, even if it had technically advanced ideas.

Give me some time and I will give you some more information on the Euler planes.

I tried to make an succinct overview of the Voisin-like biplanes built by Euler and his Euler Flugmaschinen-Werke.

It was not easy, since almost each of the one hundred or so copies was a unique specimen with a number of differences. Nevertheless I tried …

In 1908 August Euler obtained a licence from Voisin to build his well-known pusher biplane. Voisin had to deliver to Euler a copy of his biplane, but since the French authorities were opposed to a technology transfer to Germany the copy sent had a number of outdated or useless parts, and was unable to fly…! Between Euler and Voisin a conflict ensued and Euler decided to build and adapt on his own the basic Voisin design.

1. Standard Voisin biplanes (built in 1909). Two built, and with the second one (with Antoinette 60 HP) Euler made a first controlled flight on August 20, 1909.

2. Modified Voisin biplanes (built in 1910). With Gnome 50 HP, except one with Argus. Built as singe-seaters, and some as two-seaters.

Indeed, early 1920s style, and apparently a R III of Stahwerk Mark. But the engine??? As far as I know the R IIIs had only low powered Haacke air cooled boxer engines, but I am not well familiar with German aviation of the 1920s.

Dr.3 was first flown in November 1917,powered by one 160 hp Mercedes D.III engineDr.4 was first flown in early 1918,powered by one 180 hp Goebel Goe III rotary engineDr.5 was a development of Vierdecker in an attempt to evolve a successful triplane fron this unsuccessful quadruplane

The 2008 publication by Michael Düsing (and its recent English translation) can be considered as the definitive Euler history, based on serious research in original archive records. It gives a list and a description of all 503 Werknummern of Euler aircraft between 1909 and the end of the Euler production after the 1918 Armistice. So there are no more Euler aircraft than those listed.

In 1917-18 five Euler triplanes were built: D.R. 4, D.R. 5, D.R. 6, D.R. 7 and D.R. 9. The exact rendering of these internal designations is indeed D.R., with dots and Roman figures. So there are no such things as "Dr.III" or "Dr.IV" or "DR IV".

Concerning the so-called "Dr 3, 4 and 5" you found in AZ Magazine:- The only Euler triplane with a Mercedes engine was the D.R. 5.- The triplane with the Goedel Goe III was the D.R. 6.- The D.R. 9 was evolved at the same time as the quadruplane D 4, and both types had common characteristics.
